I am trying to get a sprite to move and play the correct walk animation for the movement. I thought I figured it out but when I call the animation it says the sprite doesn't exist. I created the sprite well before the animation. Everything works except adding in the moveSpriteRight function and moveSpriteLeft function.

After typing everything below, I spotted your problem. You hav not declared 'digger' to be a global variable. So it is not visible to your two functions. When they try to play the sprite, they see digger as a value of zero. You should also stop playing the sprite before you set it to play a different piece, just to keep AppGameKit unconfused.

Assuming your image file is in your media directory, try using "/media/digger.png" in your loadImage call.

Also try it without resizing the sprite, just to make sure it is loading.

Are you using percentage or pixel positions? I'm guessing percentage, based on a sprite size of 10.

Cheers,

Face to palm!!! I missed the global. D'OH!!! I added in the stop sprite function. The only problem now is that it doesn't play through the sprite. It will change direction but only play the first frame of the playSprite function. Even if I take out the stop sprite it still does not work. Also I am not sure if where I put the stop sprite is the best location.

I tried your code with a blank sprite (and no animation).

The sprite didn't move.

You need to initialize the direction variable to 1. Then the sprite moves back and forth.

Also, you don't want to call moveSpriteRight/Left every loop. It constantly resets the frame. You should only call it when the direction changes. Like this:

I used your code and it worked. The only thing I was missing was to call the moveSpriteRight() at the beginning of the code.

I did not include all of my code only the part that I thought was the problem. I may have missed something.

Hello,

I have a similar problem. I have a png with 26 frames but can´t see other frames after the animation is initialized. This is driving me crazy. Tried stopanimation, resume, etc... nothing works...


SetVirtualResolution ( 640, 480 )

rem Background image 640x480
CreateSprite ( LoadImage ( "grass.jpg" ) )

rem Horse Animation (26 frames), eating:Frame 1-14, walking:Frame 15-26
horse = CreateSprite ( LoadImage ( "horse_animation.png" ) )
SetSpritePosition ( horse, 20, 200 )
SetSpriteAnimation ( horse, 144, 144, 26 )

rem Horse begins to walk
PlaySprite ( horse, 10, 1, 15, 26 )

rem Horse is not eating
eating = 0

do
if (eating = 0)
x = GetSpriteX(horse)
if (x > 480) rem After horse walks > 480 it needs to eat... And boy it will not STOP! (flag eating=1 forever)
eating = 1
PlaySprite ( horse, 10, 1, 1, 14 )
elseif (x < 480) rem If not continues walking
SetSpritePosition ( horse, x+1, 200 )
endif
endif
Sync ( )
loop

OPS! Sorry, my mistake at elseif (x < 480) must be (x <= 480)... Fixed...

Well, not to loose the travel... How to put a Code snipet in the message ?

Can you post the image you are using? Then I might try your code.

Also, you are using a frame rate of 10 to display 11 and 14 frames. The default frame rate for apps is 60. That might have an affect on which frames you see, I'd have to play with the code to check that.

Edit: What version of AppGameKit are you using? And, are you seeing this on your PC or in a Player? If in a Player, how sure are you that it is the same version as your PC AppGameKit?

I spent the whole day trying to find a bugg in my code as the spike traps did show on my computer but not on android.

The problem whas that i neaded to start the file manager and delete the game project inside the agk folder on the phone.

The player didt update the map file when i broadcasted it to the phone
